NAME

stdio.h, stdio - standard buffered input/output

SYNOPSIS

#include <stdio.h>

DESCRIPTION

The <stdio.h> header defines the following macros as positive integer constant expressions:

BUFSIZ

: size of <stdio.h> buffers

_IOFBF

: input/output fully buffered

_IOLBF

: input/output line buffered

_IONBF

: input/output unbuffered

L_ctermid

: maximum size of character array to hold ctermid() output

L_tmpnam

: maximum size of character array to hold tmpnam() output

SEEK_CUR

: seek relative to current position

SEEK_END

: seek relative to end-of-file

SEEK_SET

: seek relative to start-of-file

The following macros are defined as positive integer constant expressions that denote implementation limits:

{FILENAME_MAX}

: Maximum size in bytes of the longest filename string that the implementation guarantees can be opened.

{FOPEN_MAX}

: Number of streams that the implementation guarantees can be open simultaneously. The value is at least eight.

{TMP_MAX}

: Minimum number of unique filenames generated by tmpnam(). Maximum number of times an application can call tmpnam() reliably. The value of {TMP_MAX} is at least 25. On XSI-conformant systems, the value of {TMP_MAX} is at least 10000.

The following macro name is defined as a negative integer constant expression:

EOF

: end-of-file return value

The following macro name is defined as a null pointer constant:

NULL

: null pointer

The following macro name is defined as a string constant:

P_tmpdir

: default directory prefix for tempnam()

The following is defined as expressions of type "pointer to FILE" point to the FILE objects associated, respectively, with the standard error, input, and output streams:

stderr
